mail_max_userip_connections per remote IP not working

[Alessio Cecchi]

Hi,

I'm tryng to set a specific mail_max_userip_connections for a remote IP 
(webmail IMAP software), but it seems not working:

remote 1.2.3.4 {
   protocol imap {
     mail_max_userip_connections = 100
   }
}

and also this isn't working

remote 1.2.3.4 {
     mail_max_userip_connections = 100
}

I insert it at the end of 20-imap.conf file.

Is something wrong or is not supported?

I'm running dovecot 2.3.14.

Thanks
